abbott spinal cord stimulator mri safety

The IPG should be placed into the pocket, at a depth not to exceed 4 cm (1.57 in), with the logo side facing toward the skin surface. To correct the effect of interference with other devices, turn off the equipment or increase the distance between the equipment and the device being affected. Follow proper infection control procedures. During RF lesioning procedures, the radiated electrical fields may interfere with other electrical medical equipment. Package or component damage. In the clinical experience with this device, patients have experienced few effects when moving from lying down to sitting up. Warn patients to seek medical guidance before entering environments that could adversely affect the operation of the implanted device, including areas protected by a warning notice preventing entry by patients fitted with a pacemaker. This neurostimulation system is designed to deliver low-intensity electrical impulses to nerve structures. Dispersive connections. If radiation therapy is required, the area over the implanted IPG should be shielded with lead. Diathermy therapy. Inspect the generator and reusable accessories before each use. For Radiologists and MR Technologists 1) Confirm MRI Readiness. Sheath rotation. For Spinal Cord Stimulation Systems. Abbott’s advanced neurostimulator systems are designed to maximize patient outcomes by using the lowest effective dose of stimulation and tailoring therapy to each person.1,2 Whether your patients experience chronic pain focally, or broadly across their body, our advanced approach to neurostimulator technology can provide relief. Patients should be advised to not use therapeutic magnets. Advise patients to use caution when undergoing any procedure that could include radiofrequency (RF) or microwave ablation, defibrillation, or cardioversion. Programmer and controller devices are not waterproof. To prevent injury or damage to the system, do not modify the equipment. Efficacy of Burst Spinal Cord Stimulation Microdosing in a De-Novo Patient: Preliminary Analysis. Postural changes. Patient Controller App, 3875 Always remove the trial leads before implanting the implant leads to avoid the risk of infection that may cause death if the leads are not removed. In addition to those risks commonly associated with surgery, the following risks are associated with using this neurostimulation system: Unpleasant sensations or motor disturbances, including involuntary movement, caused by stimulation at high outputs (if either occurs, turn off your IPG immediately. To minimize or prevent the implanted cardiac system from sensing the output of the neurostimulation system, (1) maximize the distance between the implanted systems; (2) verify that the neurostimulation system is not interfering with the functions of the implanted cardiac system; and (3) avoid programming either device in a unipolar mode (using the device’s can as an anode) or using neurostimulation system settings that interfere with the function of the implantable cardiac system. The neurostimulation system may interfere with the normal operation of another active implanted device, such as a pacemaker, defibrillator, or another type of neurostimulator. However, some patients may experience a decrease or increase in the perceived level of stimulation. If the patient complains of heating at the grounding pad site, stop the procedure and remove the grounding pad from the patient. If the patient is sedated, place your hand on the backside of the grounding pad, while still leaving it attached to the patient. Conscious sedation. The effect of other implanted devices, including deep brain stimulators, peripheral nerve stimulators, implanted drug delivery pumps, and cochlear implants on the neurostimulation system are unknown. Ask your If the operating field is bloody, wipe gloves, lead, stylet, and sheath before handling the lead. Electrode positioning. Additional risks to the patients, as a result of the placement and stimulation of the lead in the area of the dorsal root ganglion (DRG), include pain from setting the stimulation parameters too high. Interference with other equipment. Control of the patient controller. Safety information Some body scanners and medical imaging can interfere with the spinal cord stimulator. Expiration date. Application modification. MRI COMPATIBILITY. Memo on file. Safety and effectiveness of neurostimulation for use during pregnancy and nursing have not been established. Poor surgical risks. Operation of machines, equipment, and vehicles. Lead movement. If unpleasant sensations occur, the IPG should be turned off immediately. The IPG should be explanted before cremation because the IPG could explode. Use extreme care when handling system components. Do not crush, puncture, or burn the IPG because explosion or fire may result. Electrical medical treatment. If fluids are being used during a procedure, ensure that they are positioned away from the generator. In fact, approximately 82% of patients with an implanted spinal cord stimulation system (SCS) are expected to need at least one MRI within five years of implant. Keep programmers and controllers dry. Do not suture directly onto the lead to avoid damaging the lead. Insertion of a sheath without the lead may result in dural puncture. Physicians need to be aware of the risk and possible interaction between a neurostimulation system and an implanted cardiac system, such as a pacemaker or defibrillator. The lead-extension connector should not be placed in the soft tissues of the neck due to an increased incidence of lead fracture. Patient activities and environmental precautions. If monitoring is required, place monitoring electrodes as far as possible from the electrode. High amplitudes and wide pulse widths should only be programmed with due consideration of the warnings concerning charge densities. If the lead is unable to deploy out of the sheath, inject sterile water or saline slowly to release tissue that may have entered between the sheath and the lead. Component disposal. Your Spinal Cord Stimulator (SCS) system is designed to help you manage your chronic pain so you can live life to the fullest. Stabilizing the lead during insertion. If lithotripsy must be used, do not focus the energy near the IPG. If such exposure occurs, clean the affected parts with sterile, deionized water or sterile water for irrigation, and dry them completely prior to lead connection and implantation. Advise patients to contact their physician if they are concerned about their mobile phone interacting with their neurostimulation system. Sheath retraction. Use care when reinserting a stylet. Risk of patient injury. Device modification. Such restrictions may apply aboard airplanes, near explosives, or in hazardous locations. Coagulopathies. Spinal cord stimulation is increasingly used in patients with pain of spinal origin, particularly to manage postlaminectomy syndrome. Pressures below 30 m (100 ft) of water (or above 4.0 ATA) could damage the neurostimulation system. The MRI clinician must consult the MRI guidelines to determine how to proceed or contact Medtronic Technical Support at 800-328-0810. The IPG should be placed into the pocket, at a depth not to exceed 4.0 cm (1.57 in), with the logo side facing toward the skin surface. Bathing. The safety and efficacy for the treatment of patients who have back pain as the greatest region of pain have not been evaluated. Electromagnetic interference (EMI). Safety for use of external defibrillator discharges on a patient receiving neurostimulation has not been established. Safety information. The use of ultrasonic scanning equipment may cause mechanical damage to an implanted neurostimulation system if used directly over the implanted system. Do not use short-wave diathermy, microwave diathermy, or therapeutic ultrasound diathermy (all now referred to as diathermy) on patients implanted with a neurostimulation system. Algovita Spinal Cord Stimulation System MRI Procedure Guidelines 3 2. External defibrillators. Electrical pulses from a neurostimulation system may interact with the sensing operation of an implanted cardiac system, causing the cardiac system to respond inappropriately.
